Setting Up a User's Public Key

Public key authentication is an alternative to password authentication, providing a
more secure authentication method that allows users to avoid entering or storing a
password, or sending it over the network. It is done by using the client computer to
generate the key-pair (a public key and a private key), provide the public key to
the server or the point-to-point, and have the public key installed on that
machine.

Obtain the client's public key.

The client should send you an email with the public key, either a text string attached in
the secure email, or saved as a text file. In this example, the client's login
user account is aspera_user_1.
